Overwriting the trace
The text is printed at the normal chart
speed. There is only a brief interruption of
the channel 1 trace. No text printing at zero
chart speed and at a chart speed above
360mm/h.
Printing a text line requires different times,
depending on the programmed chart
speed.
Chart speed
5mm/h
20mm/h
120mm /h
Advantages:
- the time reference is retained during text
printing
- recording of signals on channel 1 is only
interrupted for a very brief time
- if pen offset compensation has been
switched on it need not be switched off
during text printing
Disadvantages:
- text printing may take a very long time
- there is no text printing at zero chart
speed and at chart speeds above 360mm/h
